Track changes in Excel like the same operation you’re familiar with in Word. On the Review tab, Changes group, click Track Changes and choose Highlight Changes. On the dialog box, click the checkbox on top. This also shares the workbook.
There are additional options to determine who may make changes, where to track them and which changes to track based on when the file was last updated. Choose to Highlight changes on screen, and you’ll see changed cells with a navy blue indicator triangle in the upper-left corner.
